(3+w)(5w-2)=0

Solution for (3+w)(5w-2)=0 equation:

Simplifying
(3 + w)(5w + -2) = 0

Reorder the terms:
(3 + w)(-2 + 5w) = 0

Multiply (3 + w) * (-2 + 5w)
(3(-2 + 5w) + w(-2 + 5w)) = 0
((-2 * 3 + 5w * 3) + w(-2 + 5w)) = 0
((-6 + 15w) + w(-2 + 5w)) = 0
(-6 + 15w + (-2 * w + 5w * w)) = 0
(-6 + 15w + (-2w + 5w2)) = 0

Combine like terms: 15w + -2w = 13w
(-6 + 13w + 5w2) = 0

Solving
-6 + 13w + 5w2 = 0

Solving for variable 'w'.
